Pasi pekutungamirirwa kwaSandor Kruk, kubva kuMax Planck Institute for Extraterrestrial Physics, boka renyika dzakawanda revatsvakurudzi richangowana, rakavigwa pakati pe data yakaraswa kubva kuHubble Space Telescope, anopfuura 1.000 asteroids ayo isu tisingazivi kusvika ikozvino. Muchinyorwa chichangobva kubuda mu'Astronomy & Astrophysics', chikwata chevazivi venyeredzi chakatsanangudza kuti pakuongorora mamepu akaunganidzwa naHubble mumakore makumi maviri adarika, vakawana anopfuura churu nemazana manomwe enziyo dzeasteroid. Vakawanda vavo vaitovaziva kare, asi vanopfuura 20 1.700 vakaratidza kuva vatsva zvachose.
Sezvo makore achifamba, teresikopu yakawanda uye yakawanda inoramba ichitarisisa, ichizadza mafaira edata ayo chaizvo pasina ane nguva yekuongorora.
Zvakazoitika kuti zvakakosha zvakawanikwa dzimwe nguva zvinogovaniswa mune iyo data yakamirira masayendisiti kugadzira nzira nyowani dzekuongorora uye maturusi ekuzviwana. Ndizvo chaizvo zvakabudirira mumubatanidzwa unonzi Hubble Asteroid Hunter, wakatangwa muna 2019 neboka revazivi venyeredzi semugari wesainzi chirongwa paZooniverse papuratifomu. Sezvinoratidzwa nenhamba yayo, chinangwa chaive chekuongorora Hubble data mukutsvaga maasteroid matsva.
"Mumwe marara emuchadenga anogona kuva pfuma yeumwe," akadaro Kruk. Muchokwadi, iyo data yakaongororwa yainyanya kuraswa kubva kune dzimwe cherechedzo dzaive dzisina chekuita neasteroids uye ingadai yakanzi 'ruzha'. Asi iyo data yese yakaraswa uye isina kumboongororwa nemunhu yakaramba yakanyatsochengetedzwa uye iripo. "Huwandu hwemashoko akaunganidzwa muzvinyorwa zvekuongorora nyeredzi - anodaro Kruk- anowedzera zvakanyanya uye isu taida kushandisa iyi inoshamisa data".
Saka, chikwata chakaongorora mifananidzo inodarika 37.000 yeHubble yakatorwa pakati paKubvumbi 30, 2002 naKurume 14, 2021. mutsara wakakombama wakadhindwa pamufananidzo. Kuwana iyi mitsetse yekutaura, zvisinei, ibasa rakaoma kumakomputa, uye ndipo panopinda Zooniverse chikuva nesaenzi yevagari.
"Nekuda kwekutenderera uye kufamba kweHubble pachayo - anotsanangura Kruk - mwaranzi inoratidzika yakakomberedzwa mumifananidzo, izvo zvinoita kuti zviome kurongedza nzira dzeasteroid kana, asi, zvakaoma kuti komputa inzwisise kuti ingangozviona sei. Saka taida vazvipiri kuti tiite danho rekutanga, iro ratakashandisa kudzidzisa muchina kudzidza algorithm. "
Danho iri rakabudirira, uye vazvipiri 11.482 vakapinda muchikamu chemifananidzo, nemhedzisiro ye1.488 yakanaka classifications mune ingangoita 1% yehuwandu hwehuwandu hwemifananidzo. Idzi data rakazoshandiswa kudzidza muchina wekudzidza algorithm yekutsvaga yasara mifananidzo yeHubble, iyo yakadzosa mazana mapfumbamwe ekuonekwa.
Uye ndipo pakapinda nyanzvi dzenyeredzi. NaKruk ari pachitsigiro, vazhinji vevanyori vemapepa vakaongorora zvakabuda, vasingabatanidzi miranzi ye cosmic nezvimwe zvinhu. Pakupedzisira, pakanga pane 1.701 yakasimbiswa asteroid tracks yakasara, iyo 1.031 yakanga iri itsva zvachose uye isingazivikanwi.
Vanotsvaga vanoti kusvika parizvino vatiza kuonekwa nekuti vanyanya kufenda uye vangangove vadiki pane vakaonekwa neteresikopu. Chinyorwa ndicho chikamu chekutanga chebasa rakaoma mukati meHubble Asteroid Hunter initiative. Muchikamu chinotevera, masayendisiti achashandisa chimiro chakakombama chezvipingamupinyi kuona matenderedzwa nemadaro emaasteroid matsva.
"Asteroids - inoenderera mberi Kruk - zvisaririra zvekuumbwa kweSolar System yedu, izvo zvinoreva kuti tinogona kudzidza zvakawanda nezvemamiriro aivepo mairi pakazvarwa mapuraneti."
Muongorori zvakare anovimbisa kuti timu yake yakawana, kunze kweasteroids, imwe data: "paivewo nezvimwe zvakapusa zvakawanikwa mumifananidzo yekuchengeta, uye ikozvino tiri kuzvidzidza". Asi Kurk haasati akuda kuburitsa zvirimo mune izvi 'zvimwe zvakawanikwa'. Nokuda kwaizvozvo tichafanira kumirira zvishoma.
